High Volume Booster VB2 – Design & Performance Features

  • QUICK RESPONSE :
    Provides large volume for rapid stroking of the actuator when confronted with input signals exceeding preset magnitude and rate capabilities. Stroking period can be reduced from one minute to less than three seconds using 3/4” High Volume Booster on 300 sq. inch diaphragm actuator having 3 1/2” stroke.
  • GREATER STABILITY :
    Allows normally slow actuator response to the small or slow signal changes produced by usual process variations.
  • LOW AIR CONSUMPTION :
    Soft seats provide tight shutoff to prevent unnecessary air consumption.
  • ACCURACY :
    Maintains correct actuator position at high stroking speeds.
